Does the same app work if you flash it directly (ie to clean device, not via OTA)?

What version of IDF was the new app built with? And what version of IDF was used for the bootloader that is on the device using OTA? (The bootloader version should be logged as part of booting).

There was a bug fixed recently for backwards compatibility of newer IDF apps with pre-v2.1 bootloaders.

It not happen everytime so I don't know why?

Do you mean every time you run the OTA update, or every time you reset with the same app on the flash?

Yes. Actually I use example in IDF for OTA app.

I have updated the lastest.

It's not happen every time I reset with the same app on the flash. Just sometime.

New: If OTA app and factory app is the same, it not happen.
